Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and more particularly to a handcart for harvesting goji berries. Background Technology

[0002] Goji berries are characterized by their thin skin, high water content, and high sweetness. Harvesting them is primarily for drying purposes, so it's best to pick only the fruit, excluding the stem. Numerous mechanical devices have been disclosed for goji berry harvesting. For example, patent number 202311626074.1, entitled "A Handheld Vibrating Brush-Type Goji Berry Harvesting Device," includes a handle, an optical axis fixing mechanism, a vibration mechanism, a brushing mechanism, and a collection mechanism. It uses the combined vibration and brushing actions to harvest mature goji berries. Another example is patent number 202311249840.7, entitled "A Goji Berry Harvesting Device," which includes a support and movement mechanism; a harvesting mechanism for vibrating and harvesting goji berries; and an adjustment mechanism located between the support and movement mechanism to adjust the position and angle of the harvesting mechanism relative to the support and movement mechanism. During the operation of the goji berry harvesting device, when the supporting moving mechanism moves to a suitable goji berry tree, the posture adjustment mechanism adjusts the harvesting angle of the harvesting mechanism according to the growth of the branches, ensuring it is perpendicular to the branches. Once there are no more fruits on the branches, the position is readjusted until the entire goji berry tree is harvested, greatly improving harvesting efficiency while reducing labor costs. Goji berry harvesting generally combines vibration and harvesting methods. Summary of the Invention

[0003] Based on the above description, the hand-push goji berry picking vehicle proposed in this utility model realizes the horizontal reciprocating movement of several rows of brush devices through the control of the crank slider device by the speed reducer. The flexible bristles on the several rows of brush devices can simultaneously pick the mature goji berries on the whole goji berry tree and collect them through the collection box.

[0004] The technical solution adopted is: a hand-push goji berry picking cart, including a baffle, a brush device, a crank-slider device, a slide, wide wheels, a collection box and a base box; profiles are fixed around the baffle, a crossbar is fixed in the middle, and a slide is fixed on the crossbar; a vertical bar is fixed on one side of the slide, and several brush devices are fixed on the vertical bar; a crank-slider device is fixed on the slide.

[0005] The base box is fixed to one side of the lower part of the baffle, and a bracket is installed on the other side of the lower part of the baffle, on which the collection box is placed; the bottom of the base box and the bottom of the bracket are on the same horizontal line; at least one wide wheel is installed on the bottom of both the base box and the bracket, fixing the base box and the bracket to the lower part of the baffle; the collection box is located below the brush device.

[0006] The slide table includes a slide rail and a slider. The slider works with the slide rail to enable the slider to move on the slide rail. The slide rail is fixed to a horizontal bar. A vertical plate is fixed to one side of the slider.

[0007] The crank-slider device includes a reducer, a crank, a connecting rod, and a connecting block. The reducer is connected to a servo motor and is mounted on one side of a baffle via a connecting plate, which is embedded within the baffle. The main shaft of the reducer passes through the connecting plate and is connected to one end of the crank via a key. The other end of the crank is movably connected to one end of the connecting rod via bolts, and the other end of the connecting rod is movably connected to the connecting block via bolts. The connecting block is fixed to the upper part of the slider via bolts. The reducer drives the crank to rotate, and the crank drives the connecting rod to rotate, thus realizing the horizontal movement of the connecting block on the slider and the horizontal movement of the vertical plate on the slider along the slide rail.

[0008] Several brush devices are fixed parallel to each other on a vertical plate; each brush device includes a mounting plate and flexible bristles; several flexible bristles are fixed on the mounting plate; the mounting plate is fixed on the vertical plate.

[0009] Furthermore, the bracket includes a first side plate, a second side plate, and a base plate, which are integrally formed; the first side plate is fixed to the baffle; a wide wheel is fixed on the base plate; the second side plate is perpendicular to the first side plate and the base plate respectively.

[0010] Furthermore, a handle is provided on one side of the baffle; one end of the handle is fixed to the bottom of the bracket, and the other end is fixed to the bottom of the base box.

[0011] Furthermore, the flexible bristles are fixed to the mounting plate in an interlaced pattern.

[0012] Furthermore, the power supply and controller are installed inside the base box.

[0013] This utility model features a simple structure, low cost, and high efficiency in harvesting goji berries. A servo motor and reducer, along with a crank-slider device, drive a connecting block and slider to move horizontally along a slide rail. A vertical plate is fixed to one side of the slider, enabling the horizontal movement of the vertical plate. Several brush devices are mounted parallel to each other on the vertical plate, achieving horizontal reciprocating motion. The flexible bristles on the brush devices are fixed to the mounting plate in an alternating pattern, increasing the contact area between the brush devices and the goji berries. This allows all mature goji berries from the entire tree to be brushed off simultaneously and fall into a collection box below. An empty collection box is placed on the bottom for easy replacement.

[0014] During actual harvesting, the height of the brush device can be adjusted according to the height of the goji berry trees on site to increase the actual harvesting rate. Attached Figure Description
